Product introduction:

The louder the sound, the more the LED will light up from left to right. As the sound fluctuates, the LED will jump with the music, especially when playing DJs.

Audio input:

1. The board comes with a microphone with high sensitivity, which can sense and receive external sound sources to control the flickering of the LED lamp beads. The disadvantage is that it is easily affected by other external sounds.

2. If you need line input, please insert the 3.5mm plug into the earphone jack of the mobile phone or computer. This interface cannot be connected to the output or speaker end of the power amplifier, because the signal is too strong and belongs to high potential. If you want to DIY, you need to attenuate the signal.
